Hi, I have a simply report and would like to pass multiple INT value parameter (Product ID 'int') when I am running the report. When I choose the single value (Product ID), it runs well. But when I choose more than one value, in the report preview, it shows 'Error converting data type nvarchar to int' . Does anyone have any idea about fixing this 'simple' problem? I think maybe i need to convert the parameter in SP. But I tried 2 days and got nothing. Realllllly Appreciate It!!
